Tank weighing solution (tanks, hoppers, reactors)

Chemical companies use many types of storage and metering tanks in their processes. Two common problems are metering materials and controlling production processes. In our experience, we can solve these problems by using electronic weighing modules.
You can install the weighing module on containers of any shape with minimal effort. It is suitable for retrofitting existing equipment. A container, hopper, or reaction kettle can become a weighing system. add a weighing module. The weighing module has a big advantage over off-the-shelf electronic scales. It is not limited by available space. It is cheap, easy to maintain, and flexible to assemble. The container’s support point holds the weighing module. So, it does not take up extra space. It is ideal for tight spaces with side-by-side containers. Electronic weighing instruments have specs for the measuring range and division value. A system of weighing modules can set these values within the instrument’s limits. The weighing module is easy to maintain. If you damage the sensor, adjust the support screw to lift the scale body. You can then replace the sensor without removing the weighing module.

Weighing module selection plan

You can apply the system to reaction vessels, pans, hoppers, and tanks. This includes storage, mixing, and vertical tanks.

The plan for the weighing and control system includes multiple components: 1. multiple weighing modules (the FWC module shown above) 2. multi-channel junction boxes (with amplifiers) 3. displays

Weighing module selection: For tanks with support feet, use one module per foot. Generally speaking, if there are several support feet, we use several sensors. For a newly installed vertical cylindrical container, three-point support offers a high level of stability. Of the options, four-point support is best. It accounts for wind, shaking, and vibration. For containers arranged in a horizontal position, four-point support is appropriate.

For the weighing module, the system must ensure that the fixed load (weighing platform, ingredient tank, etc.) combined with the variable load (to be weighed) is less than or equal to 70% of the rated load of the chosen sensor times the number of sensors. The 70% accounts for vibration, impact, and partial load factors.

The tank’s weighing system uses modules on its legs to collect its weight. It then sends the module data to the instrument via a junction box with one output and multiple inputs. The instrument can display the weight of the weighing system in real time. Add switching modules to the instrument. They will control the tank feeding motor via relay switching. Alternatively, the instrument can also send RS485, RS232, or analog signals. This transmits the tank weight to control equipment like PLCs for complex control.
